Abstract
A capacitor comprises a pair of electrodes separated by a dielectric comprising a phthalate polyester of a bis-hydroxyphenyl-alkane(bis-phenol) wherein the alkane group contains 1 to 5 carbon atoms and the phthalate radical contains 50-100 mole per cent isophthalate and 50-0 mole per cent terephthalate radicals. The bisphenols may be of structure <FORM:1022219/C3/1> where n is an integer 0, 1, 2; R1 is a lower alkyl radical of 1 to 8 carbon atoms and R is a divalent saturated aliphatic group, i.e. alkylene or alkalidene of 1 to 5 carbon atoms. R1 may be methyl, ethyl, propyl, isopropyl, butyl, secondary butyl, tertiary butyl, isomeric hexyl, heptyl, octyl etc., while R may be methylene, ethylene, ethylidene, propylene, propylidene, isopropylidene, 1,4-butylene, 1,3-butylene, 2,3-butylene, 2-methyl propylidene, 2,2-butylidene, 1,2-, 1,3-, or 2,4-pentylene, 1,1-, 2,2-, 3,3-pentylidene, and isopentylidenes, e.g. diethyl methylene, methyl propyl methylene, and the like. The hydroxyl group may be in the ortho, meta or para position. The polyesters are preferably synthesized either by esterification of the bisphenol as its preformed lower alkyl monocarboxylic acid esters, e.g. the diacetate of the bisphenol, or by esterification in situ by using the anhydride of the lower alkyl monocarboxylic acid. The alkyl esters of the bisphenol are reacted with isophthalic acid which may contain up to 10 mole per cent of terephthalic acid; with a solvent of, e.g. diphenyl, diphenyl ether, naphthalene, or their halogenated or hydrogenated derivatives. The reaction is carried out preferably at the reflux temperature of the mixture, so that the polymer is not precipitated, in an inert atmosphere of, e.g. nitrogen until no more of the lower alkyl monocarboxylic acid, which is initially esterified with the bisphenol, is expelled and until the desired viscosity is attained, after which the mixture is cooled to a temperature at which it is homogeneous, and a solvent, e.g. o,m,p-cresol; mixed cresylic acids, dimethyl acetamide, benzonitrile, N-methyl pyrrolidone and the like is added to give a final composition containing 15-20% resin solids. The films of dielectric may have metallized conducting layers coated thereon or be coated on metal foils; or glass, asbestos or textile cloth may be impregnated or coated therewith and used as dielectric. The polyester may be co-esterified with a diphenolic acid to the extent of 1 to 10 mole per cent to improve the thermal properties, or may be cross-linked by exposure to radiation. Specific examples of the preparation of particular bisphenols are set forth.
